Frenchtown Flyer, I will take your advice and do 3 angles on the valve seats. I work in a truck shop and all we do is swap complete heads.(CAT reman ect.) Couple that with the fact that until recently I had no need to build an engine,(Grandson changed that) the polite way of putting it is I am a "little"rusty at best. One thing I do know from user experence: There is big difference between vortec (good flowing)and non-vortec heads. (305). A lump ported,ported head is out of the budget,plus I want to try something different. I also hope to contrubuite some information and not just take info that you and others have worked so hard to get. Who knows maybe someday I will be king of "The land of misfit cylinder heads" LOL Jay
